groove with subcarinate edges extends into and divides the 

 bioad, deep, semicircular, basal fossa, and is prolonged as a 

 carina to tlie basal margin ; lateral fovese deep and prolonged 

 forwards as distinct grooves, between these and the median 

 groove the snrf'ace is somewhat ridged longitudinally towards 

 the base. Klytra subquadrate, slightly longer and evidently 

 broader than the thorax, slightly curvedly narrowed at the 

 shoulders ; sutural strise deep, broad, and distinctly fovei- 

 form at the base ; dorsal impressions short, broad, and deep. 

 Hind body with deflexed apical segments, so as to seem 

 sliorter than the elytra ; first segment with a fine carina at 

 each side of the feeble median impression at the base, second 

 horizontal and about as long as the first. 



Femora robust, the posterior much less so ; the intermediate 

 tibiee gradually yet considerably expanded towards the extre- 

 mity, which is deeply notched. 



Antennce shorter tiian tlie head and thorax, moderately 

 slender, with the terminal joints almost forming a triarticulate 

 club; second joint quite oblong and rather longer than the 

 exposed portion of the basal one, third rather longer than 

 broad, obconical, much smaller than second; joints 4-8 sub- 

 moniliform, small, broader than long, fifth and seventh 

 slightly larger than adjacent ones ; ninth subquadrate, twice 

 as large as its predecessor and longer than the transverse 

 tenth, the terminal conical and subacuminate, as long as the 

 preceding two combined, 



Male. — Metasternum broadly impressed. Basal ventral 

 segment covered by the femora, ciliate behind, 2-4 equal, 

 fifth widely incurved, the middle hardly more than half the 

 length of the fourth; sixth longer than fifth, widely, deeply, 

 and angularly emarginate; seventh also large and broad. 



I'he male of E. carinatus, 3204, has the sides and base o£ 

 the thorax rather coarsely punctate, but the basal fossa is not 

 so deep ; the legs are evidently thicker, and the middle tibiae 

 are not only thicker but also shorter and less deeply notched 

 at the extremity ; the anterior tibise have along the inside 

 near the apex a fringe of yellow pubescence which is lacking 

 in this species, and the insect itself is smaller. E. schizo- 

 cneniis, 3203, may be distinguished by the coloration, even 

 and less deeply marked thorax, without the least sign of 

 longitudinal ridging; the elytra are gradually narrowed 

 from near their apices to the base and their strise are not so 

 deep ; the thighs are much stouter, the intermediate tibise are 

 broader, the apical excision is larger and the outer angle 

 more prolonged, and the head is only obsoletely punctured.
